Because retooling is expensive. I applaud the adaptation, but we have a lot of tools written that way. Also, are patents written in English or metric units? Would that invalidate them?

It wouldn’t invalidate them because customary is defined by metric, so there’s no ambiguity. It’s exactly the same as saying “the bar is 1 meter long” vs “the bar is 100 centimeter long”. An inch is just a quaint way to write 25.4 mm.

Because it provides zero practical benefit for the vast majority of people.
There’s no reason to other than to be the same as everyone else, and we already are for anything scientific or medical.
the same reason they don’t speak french.
you can use metric, just like you can speak french.
but people will think you’re talking gibberish.
